'non-expansionist' originates from the prefix 'non-' meaning 'not' and the word 'expansionist,' which comes from 'expansion,' derived from Latin 'expansio,' meaning 'a spreading out.'

'expansio' transformed into the French word 'expansion,' and eventually became the modern English word 'expansion' through Middle English.

Initially, it meant 'a spreading out,' but over time it evolved into its current meaning of 'growth or increase in size or scope.'
